A. Lesion map of CAA-related ICH group. B. Lesion map of deep ICH group. Units on color scale represent number of patients with a lesion in each area.
Cognitive impairment following intracerebral hemorrhage (ICH) has received far less attention than cognitive impairment following ischemic stroke. Most studies have focused on cerebral amyloid angiopathy (CAA) and brain microbleeds, but comprehensive neuropsychological assessment has rarely been conducted. However, recent evidence supports the notion that intracerebral hemorrhage and dementia are closely related, and that each increases the risk for the other.
The most impaired cognitive process in the CAA group with a mean performance more than 2 SDs below the norm of controls was naming followed by processing speed, executive functioning and memory; iii) there was no difference in cognitive patterns after either a CAA-related or a deep ICH; iv) cognitive dysfunctions in ICH patients were different from those in MCI-AD patients.
